创建4个文件
Activity、presenter、module、constract

在接口类constract中创建两个内部接口类：View和Presenter。暴露需要的接口方法
Contract

public interface TestContract {
    interface View extends BaseView {
        void onSuccess(Object obj);
    }

    interface Presenter extends BasePresenter {
        void getList(Object obj);
    }
}

Activity继承BaseActivity并实现刚刚的内部接口View
通过注解注入presenter对象
在onCreate中调用presenter.takeView(this)
在onDestory中调用presenter.dropView

package jay.com.example.firstapp;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
//定义MainActivity继承Activity类
public class MainActivity extends AppCompatActivity {
    @Override
    //实现onCreate方法
    protected void onCreate(Bundle savedInstanceState) {
    //调用父类
        super.onCreate(savedInstanceState);
    //加载R.layout.activity_main布局文件
        setContentView(R.layout.activity_main);
    }
}

需要在AndroidManifest.xml里声明
